Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.3.0.0, contains an improper privilege management vulnerability in the OS. A high privileged attacker with local access could potentially exploit this vulnerability, leading to elevation of privileges.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is an improper privilege management vulnerability in the operating system of Dell ECS and ObjectScale storage platforms. A high-privileged attacker with local access to the system could potentially exploit this vulnerability to elevate their privileges further, likely by manipulating OS-level permissions or user account settings.

MitigationUpgrade Dell ECS to version 3.8.1.8 or later, and Dell ObjectScale to version 4.3.0.0 or later. Apply the appropriate patch or update through Dell's official support channels, and verify the upgrade in a test environment before production deployment.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed Dell storage product
    Run command to determine if Dell Elastic Cloud Storage or Dell ObjectScale is installed on the system (e.g., check for product-specific processes, services, or installed packages)
    Affected if The system is running either Dell ECS or Dell ObjectScale storage platforms
  2. Determine the installed product version
    Use product-specific command or configuration file to retrieve the exact version number of Dell ECS or ObjectScale (consult Dell documentation for version check commands)
    Affected if The exact version cannot be determined or the product is unversioned
  3. Compare version against affected ranges
    Check if the installed version falls within: ECS 3.8.1.0 through 4.2.x (anything less than 4.3.0.0 but >= 3.8.1.0), or ObjectScale any version below 4.3.0.0
    Affected if Installed version is within the affected ranges: ECS >= 3.8.1.0 and < 4.3.0.0, or ObjectScale < 4.3.0.0
  4. Verify presence of high-privileged local accounts
    List local user accounts with elevated privileges (administrator, root, or product-specific admin accounts) that exist on the system
    Affected if High-privileged local user accounts are present on the system

The system is affected if it runs Dell ECS version 3.8.1.0 through 4.2.x or any ObjectScale version below 4.3.0.0, and has high-privileged local user accounts that could be manipulated for privilege elevation.

Upgrade available Upgrade to 4.3.0.0 or later
Fixed in 4.3.0.0
Interim mitigation

Upgrade Dell ECS to version 3.8.1.8 or later, and Dell ObjectScale to version 4.3.0.0 or later. Apply the appropriate patch or update through Dell's official support channels, and verify the upgrade in a test environment before production deployment.

Recommended fix Moderate confidence

Upgrade to Dell ECS or ObjectScale version 4.3.0.0 or later

  1. Contact Dell support or visit dell.com/support to obtain the upgrade to version 4.3.0.0 or later for Elastic Cloud Storage and ObjectScale
  2. Review Dell's upgrade documentation for ECS or ObjectScale before initiating the upgrade
  3. Schedule an appropriate maintenance window for the upgrade
  4. Execute the upgrade following Dell's documented procedures
  5. Verify the upgrade was successful and the system is functioning normally
  6. Confirm the new version is 4.3.0.0 or later
Caveat Review Dell upgrade documentation for any potential compatibility or configuration changes when moving to version 4.3.0.0
